A cam drum 43 with groove cams 44, 45 and 46 is fastened to the shaft 40. A journal bracket 48 with a. plurality of bearings, and a journal bracket 49 also with a plurality of bearings are supported on the table 20. Spindles 50, 51, 52 are supported in the accompanying bearings of the brackets 48 and 49. To the spindle 50 are fastened the arms 55 and 56, to the spindle 51 are fastened the arms 57 and 58 and to the spindle 52 are fastened they arms 59 and 60. The arms 55, 57 and 59 have respectively journaled at their upper ends the rollers 61, 62 and 63, which respectively engage the groove cams 44, 45 and 46.

On the table 20 are supported the journal brackets 65, 67, and in the latter is journaled a sleeve 70 that has formed therewith a disk 71 having a notch 72. ,A cam 75 is fastened to the shaft 40 and a lever 76 is pivoted to the bracket 65. A roller not shown is journaled to one end 0f the lever 76 and at the other end of the lever is formed the toe 79, which is in the path of the notch 72.

A sector 80 on the shaft 40 can mesh with a gear 81. A gear 83 on the sleeve 70 meshes with the gear 81. A tubular sleeve 86 is supported in the sleeve 70, an intermediate sleeve 87 is supported in the sleeve 86 and a third sleeve 88 is supported in the sleeve 87. A rod 90 is slidably supported in the sleeve 88. p

A bracket 92 with the'secondary bracket 93 for the rod 90 extends up from the table 20. A bracket 95 on the rod 90 supports a pin 98. A link 99 has one end connected to the pin 98 and the other end is pivoted to the lever 103, which has a roller 104 to bear against the cam 42. An arm 105 carries one end of a spring 106, the other end'of which latter is connected to the lever 103. A collar 112 on the sleeve 86 is connected by a link 114 to the arm 60. A collar 120 on the 90. Brackets 175, 176 extend from thetableV 20 and carry the frame plate 177, having the opening 178. The plate 177 carries the uprights 179 and 180 which are connected by the upper tie braces 183, 184 and theV lower similar tie braces like 181. The upright 179 has formed therein a slot 185 for the pusher block 186. A pusher plate 187 is carried on the block 186.

On the up-right 179 is fastened a threaded bracket 189 with the adjusting 'screwV 190. The screw constitutes an adjustable stop for the pusher block 186. A link 192 has one end pinned to the pusher block 186 and its other end is pinned to one end ofthe lever 193, which in turn is pinned to the tie brace 184 by means ofthe pin 194. A bellV crank with the arms 196, 197 is pivoted to one of the tie braces 181. The arm 196 carries a pin 199 on which is pinned one end of the link 200, and the latter is connected to the lever 193. The arm 197 has journaled thereto the roller 202.

A pin 204 extends from the upright 179 and a pin 205 extends from the upright 180, which respectively support the pulleys 206 and 207. A guide bar 208 is also supported on the pins 204, 205. A sliding carriage 209 is supported on the guide bar 208 and carries the bracket 210, that carries the pressure plate 212. A band 217 extends from the carriage and passes over the pulley 206, then over the pulley 207, next under the suspended pulley 218. It carries the Weight 219 and finally is fastened to the hook 200 extending from the lower face of the table 20.

A carriage 222 with the table 223, lug 230 and buffer 231 is located below the braces 181. A bending arm 233 is pivoted on said carriage. A paivl 235 is pivoted on the carriage and at its upper end is pinned one end of a link 240. The other end of the lattery is pinned to the lever 242 carrying the roller 245, Which bears against a cam not shown.

A bracket 27 9 on the table 20 supports a closer 280 which is fully described in the original. application. A bracket 335 With a stop 334 is supported on the table20 and from which extends a guide block 336 for a carriage 337, having extending therefrom the stop pins 332 and A erosshead 338 is slidably supported in the carriage 337. A link 339 is pinned to the crosshead 338 by means of the pin 340. A Washer 341 surrounds the crosshead 338 bearing against the pin 340 extending from the link 339. A spring 343 bears bet-Ween the Washer 341 and the carriage From the crosshead 338 extends a. screwvpin 344 and a pin 345 extends from the carriage 337, the latter supports the blades 346, 347 that constitute shears. Slots 348, 349 are respectively formed in the blades 346, 347 and engage the screw pin 344. A spring 351 fastened to the carriage 337 encircles the pin 345 and hears on the outer blade 347 of the shears.

A bracket 352 on the table 20 supports a pin on which is pivoted an arm 354, the latter .in turn by means of the pin 355 is pivoted to the link 339. A sprinvI 356 extends between the arm 354 and the bracket 335.

A roller 361 is journaled on a pin 362 that extends from the arm 354, and a cam 363 on the shaft 40 is in the path of the roller 361.

An arm 364 extends from the bracket 175 and has pinned to its outer end a link 365. A bracket 366 on the table 20 has pivoted thereto the lever 368 which in turn is'pinned to one end of the link 369, the other end of which latter is pinned to the link 365. A roller on the lever 368 is in the path of a cam 371 on the shaft 40. To the arm 364 is also pinned the link 372 that has journaled thereto the roller 373. A pin 374 on the link 372 is in the path of the link 365. A glue box 375 is fastened to the table 20 and has journaled therein the glue Wheel 377 and spindle 379 with the cleaning blade 378. A pair of Wheels 387 for the paper band 389 are journaled ybelow the glue box. A leg 390 has pivoted thereto an arm 392 With the counterweight 393, which forces a presser linger 394 against the band 389. A band 403 with the Weight 404 has one end fastened to the link 372. It passes over the sheave 402 journaled in the arm 401 extending from the said glue box. A supporting plate 405 is hinged to the arin 364.

To operate the machine the paper band 389 is led from its reel until it reaches the carriage 222, over the edge of which latter it is bent by the bending arm 233.

A plurality of paste board strips 421 preferably notched at 422 are located, to enable them to be shaped to form the necks or frames to be made, between the tie braces 181, 183 and 184. The pressure plate 212 bears against said strips by virtue of the resulting effect of the Weight 219, and the said pressure plate maintains them with the requisite frictional engagement between said plate `and the upright 179. The shaft 23 is rotated by means of a belt not shown engaging the pulley 28. rlhe pinion 32 and gear 41 transmit rotation to the cani shaft 40. The sector 80 rotates the gear 81 and the latter rotates the gear 83, by virtue of which the guide box 135 and the blocks 145, 146 are given their requisite intermittent rotations.

lVhen the guide box 135 and blocks 145, 146 are at rest and in proper position, the strips 421 are pushed down consecutively one after the other through the opening 178, by the pusher plate 187, the strip adjacent to the upright 179 being the one that is acted upon. The strips travel to the lower end of one of the accompanying sides of each of said blocks. After each strip has been lovvered in position the pusher plate 187 rises, and the rubber buffer 231 pushes the paper band 389, which has been glued by the glue Wheel 377, against the strip. Before the guide box 135 and blocks 145, 146 have-made a complete revolution by virtue of the action of their driving mechanism, the paper band is cut by means of the blades 346, 347 of the shears. The shears are operated by the cam 363 engaging the roller 361 against the tension of the spring 356.

The cam 363 moves the link 339 in the direction of the arrow A shown in Fig. 3, by reason of which the ycarriage 337 moves in the same direction, as also the blades of the shears. lVhen the stop pin 333 strikes the stop 334, the carriage is stopped and the screw pin 344 engaging the slots 348 and 349 causes the shears to close. By the movement of the arm 354 in an opposite direction, the screw pin 344 causes the blades 346 and 347 to open, and the carriage moves to its former position. The pin 332 in case the blades should not open bv the action of the spring 343 will strike the stop 334 and the said blades will be opened. After the band has been severed the bending arm 233 bends it by gravity in the path of the buffer 231.
